The overarching message from the growth literature is that a transition from the low-productivity agricultural sector to the high-productivity manufacturing sector is necessary for structural change. Although sub-Saharan Africa has experienced substantial economic growth rates, rural–urban migration contributed very little to this progress. Migration to peri-urban areas may offer prospects for diversification out of agriculture with lower moving costs and job-search frictions than urban centers. We document migration patterns and worker selection into peri-urban and urban areas in Tanzania. Standard spatial classifications mask the prominent phenomenon of peri-urban (rather than rural) to urban migration. Lacking job experience and social networks, many youth moving to urban destinations are more likely to be unemployed. However, conditional on being employed over the two-year period of the study, migration to peri-urban as well as urban areas allows workers to transition from low- to high-valued occupations.

移民对坦桑尼亚就业和职业转变的影响

增长文献的总体信息是，从低生产率的农业部门到高生产率的制造业部门的转变对于结构变革是必要的。尽管撒哈拉以南非洲地区经历了可观的经济增长率，但农村向城市的移民对这一进展的贡献很小。与城市中心相比，向城市周边地区的迁移可能为农业多样化提供了前景，其移动成本和找工作的摩擦更低。我们记录了向坦桑尼亚郊区和城市地区迁移的方式和工人的选择。标准的空间分类掩盖了郊区（而非农村）向城市迁移的显着现象。缺乏工作经验和社交网络，许多移居城市的年轻人更有可能失业。然而，
